Title: Egg incubator
IPC: A01K41/00
Filed: 1978-03-03
Abstract: An egg incubator comprises on a front face, at least one door for the introduction thereinto of carriages with drawers containing eggs. Directing-distributing means direct a principal flow of stirring air towards said front face through which at least three series of carriages, of which one is a central series, are introduced into the incubator, and distribute by division, a part of said principal flow onto the series of carriages arranged on both sides of said central series of carriages.

Patent ES-468375-A1 (ES)
Title: Hysteresis compensated reed switch assembly for a position indicating system
IPC: H01H36/00
Filed: 1978-03-30
Abstract: The position of a control rod located within a nuclear reactor is sensed by a position indicating system utilizing low hysteresis reed switch assemblies. Each reed switch assembly includes a reed switch having an alternating magnetic flux field applied thereto through a coil surrounding the reed switch and energized by an alternating current power source. The amplitude of the alternating magnetic flux field is adjusted to be between a first flux level required to close the reed switch and a second flux level required to open the reed switch. The level of the alternating magnetic flux field is preset to be below the second flux level to maintain the switch in the open position until an external flux field is introduced to raise the total flux level above the first flux level to actuate the reed switch to close. The interaction of the alternating and external flux fields negates the hysteresis band of ordinary reed switches and provides a more sensitive and accurate position indicating circuit.

Title: Heat seal fibrous web and method of its manufacture.
IPC: D21H23/28
Filed: 1980-11-05
Abstract: Improved infusion web material for tea bags and the like is provided by using synthetic pulp in the heat seal phase and forming therein an array of a large number of small discrete craters. These craters, which exhibit an average planar area of at least about 1x10-3 square centimeters, are formed prior to drying the initially formed multi-phase material by directing a low impact mist-like liquid spray onto the heat seal phase. The droplets from the spray displace the fibers to form the shallow craters and, at times, expose portions of the underlying non-heat seal fiber phase. The small craters are present throughout the heat seal phase at a concentration of at least about 40 per square centimeter and occupy about 10-75 percent of the total exposed surface area of the heat seal fiber phase of the material. The web also is treated with a surfactant.
Patent ES-8201713-A1 (ES)
Title: Insertable-pipe connection with ring sealing.
IPC: F16L21/02
Filed: 1980-11-12
Abstract: A ring-packed pipe spigot-and-socket connection in which an elastic rubber packing ring having an essentially V-shaped cross section is disposed in an annular groove provided in the inside wall of a socket in such a way that prior to the insertion of the spigot end, one of the two legs of the V-shaped packing ring lies substantially axially aligned and turned toward the outlet of the socket, while the other leg extends substantially radially into the interior of the socket. After insertion of the spigot end, the two legs of the V-shaped packing ring provide a seal at the external wall of the spigot end. In the process, the segment of the packing ring facing the two sealing legs, i.e. the "foot segment", seals against the bottom of the annular groove. The annular groove has the shape of a substantially shallow V-shaped chamber and is of such a width that it can accommodate the spread-out packing ring completely when the spigot end has been inserted in the socket. On its two axially opposite ends, the annular groove is bound by radially extending circular ring surfaces, whose radially innermost edge is defined by the intersection of the surface with the cylindrical inside wall of the socket. The foot segment of the packing ring is of toroidal design in the manner of the ball of a ball-and-socket joint and rounded off relatively flatly or shallowly. It lies in a recess whose profile is complementary to the profile of the foot segment and which has been provided axially approximately in the center of the circular groove having been designed in a shallow V-shape. This recess acts as an annular socket like that in a ball-and-socket joint for the foot segment of the packing ring. It accommodates and blocks the foot segment of the packing ring against axial displacement, but permits flexure of the ring in the recess of the groove. The recess is preferably slightly undercut in the direction toward the base of the socket.
